Abstract
UNLABELLED Transcutaneous immunization (TCI) is a promising route of vaccine delivery through skin due to many well documented advantages. The main obstacle in TCI is the skin's top dead layer i.e. stratum corneum which is difficult to penetrate. Efficiently delivery of antigen to the immune competent cells of epidermis or dermis in TCI might elicit an effective immune response. In this review, skin immunology with a particular focus on potential of immunological active receptors in influencing adaptive immune responses is highlighted. The challenges with TCI and methods to improve it using different adjuvants, chemical and physical approaches, delivery systems, and combination of above methods to further improve immune response following skin application of antigen are elaborately discussed. Nanoparticulate vaccine delivery systems with reference to their applications in TCI are classified according to their chronological development. Conclusively, clinical translations of above methods are also briefly reviewed. FROM THE CLINICAL EDITOR Transcutaneous immunization has been investigated by many as a promising route of vaccination. In this comprehensive review article, the authors described and discussed the existing knowledge and difficulties in this approach. Furthermore, ways of improving transcutaneous delivery were also reviewed.

Investigation of microemulsion microstructure and its impact on skin delivery of flufenamic acid. Int J Pharm 2015; 490:292-7. [PMID: 26022888 DOI: 10.1016/j.ijpharm.2015.05.056] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2015] [Revised: 05/19/2015] [Accepted: 05/21/2015] [Indexed: 11/24/2022]
Abstract
Microemulsions are well known penetration enhancing delivery systems. Several properties are described that influence the transdermal delivery of active components. Therefore, this study aimed to characterize fluorosurfactant-based microemulsions and to assess the impact of formulation variables on the transdermal delivery of incorporated flufenamic acid. The microemulsion systems prepared in this study consisted of bistilled water, oleic acid, isopropanol as co-solvent, flufenamic acid as active ingredient and either Hexafor(TM)670 (Hex) or Chemguard S-550-100 (Sin) as fluorosurfactant. Characterization was performed by a combination of techniques including electrical conductivity measurements, small-angle X-ray scattering (SAXS) and nuclear magnetic resonance (NMR) self-diffusion experiments. In vitro skin permeation experiments were performed with each prepared microemulsion using Franz type diffusion cells to correlate their present microstructure with their drug delivery to skin. Electrical conductivity increased with added water content. Consequently, the absence of a conductivity maximum as well as the NMR and SAXS data rather suggest O/W type microemulsions with spherical or rod-like microstructures. Skin permeation data revealed enhanced diffusion for Hex- and Sin-microemulsions if the shape of the structures was rather elongated than spherical implying that the shape of droplets had an essential impact on the skin permeation of flufenamic acid.

Abstract
Skin is an immunologically active tissue composed of specialized cells and agents that capture and process antigens to confer immune protection. Transcutaneous immunization takes advantage of the skin immune network by inducing a protective immune response against topically applied antigens. This mode of vaccination presents a novel and attractive approach for needle-free immunization that is safe, noninvasive, and overcomes many of the limitations associated with needle-based administrations. In this review we will discuss the developments in the field of transcutaneous immunization in the past decade with special emphasis on disease targets and vaccine delivery technologies. We will also briefly discuss the challenges that need to be overcome to translate early laboratory successes in transcutaneous immunization into the development of effective clinical prophylactics.

Abstract
Microemulsions are modern colloidal drug carrier systems. They form spontaneously combining appropriate amounts of a lipophilic and a hydrophilic ingredient, as well as a surfactant and a co-surfactant. Due to their special features, microemulsions offer several advantages for pharmaceutical use, such as ease of preparation, long-term stability, high solubilization capacity for hydrophilic and lipophilic drugs, and improved drug delivery. The article summarizes the level of research with respect to dermal and transdermal application. A large number of in vitro as well as some in vivo studies demonstrated that drugs incorporated into microemulsions penetrate efficiently into the skin. The enhancing activity seems to be attributable to a variety of factors depending on the composition and the resulting microstructure of the formulations. However, an extended use in practice depends on the choice of well-tolerated ingredients, mainly surfactants, and the restriction of their amounts in order to guarantee skin compatibility.

Abstract
Cutaneous gene therapy, although a promising approach for many dermatologic diseases, has not progressed to the stage of clinical trials, mainly due to the lack of an effective gene delivery system. The main objective of this study was to construct and evaluate gemini nanoparticles as a topical formulation for the interferon gamma (IFN-gamma) gene in an IFN-gamma-deficient mouse model. Nanoparticles based on the gemini surfactant 16-3-16 (NP16-DNA) and another cationic lipid cholesteryl 3beta-(-N-[dimethylamino-ethyl] carbamate) [Dc-chol] (NPDc-DNA) were prepared and characterized. Zetasizer measurement indicated a bimodal distribution of 146 and 468 nm average particle sizes for the NP16-DNA (zeta-potential +51 mV) nanoparticles and monomodal distribution of 625 nm (zeta-potential +44 mV) for the NPDc-DNA. Circular dichroism studies showed that the gemini surfactant compacted the plasmid more efficiently compared to the Dc-chol. Small-angle X-ray scattering measurements revealed structural polymorphism in the NP16-DNA nanoparticles, with lamellar and Fd3m cubic phases present, while for the NPDc-DNA two lamellar phases could be distinguished. In vivo, both topically applied nanoparticles induced higher gene expression compared to untreated control and naked DNA (means of 0.480 and 0.398 ng/cm(2) vs 0.067 and 0.167 ng/cm(2)). However, treatment with NPDc-DNA caused skin irritation, and skin damage, whereas NP16-DNA showed no skin toxicity. In this study, we demonstrated that topical cutaneous gene delivery using gemini surfactant-based nanoparticles in IFN-gamma-deficient mice was safe and may provide increased gene expression in the skin due to structural complexity of NP16 nanoparticles (lamellar-cubic phases).

Abstract
Most current immunization procedures make use of needles and syringes for vaccine administration. With the increase in the number of immunizations that children around the world routinely receive, health organizations are beginning to look for safer alternatives that reduce the risk of cross-contamination that arises from needle reuse. This article focuses on contemporary developments in needle-free methods of immunization, such as liquid-jet injectors, topical application to the skin, oral pills and nasal sprays.

Abstract
BACKGROUND Localized scleroderma (morphea and linear scleroderma) is a connective tissue disease, accompanied by excessive proliferation and deposition of collagen within the skin, inflammation, vasculopathy and a deranged immune system. Interferon gamma (IFNgamma), an inhibitor of collagen synthesis and an immunomodulator, could be a potential therapeutic agent if it could be delivered into or expressed locally in affected skin in a non-invasive manner. In this study, the feasibility of topical delivery of the IFNgamma gene and expression of IFNgamma were investigated in mice. METHODS Novel dicationic (gemini) surfactant (spacer length n=2-16; alkyl chain m=12 or 16)-DNA complexes were formulated and characterized by circular dichroism and atomic force microscopy to select gemini analogues with the highest transfection efficiency (TE). Transfection and cellular expression of IFNgamma from the bicistronic pGTmCMV.IFN-GFP plasmid were evaluated in PAM 212 keratinocyte culture by ELISA and fluorescence microscopy. Topical delivery of plasmid using liposomal and nanoemulsion systems, based on gemini surfactant 16-3-16, was evaluated in mice by IFNgamma expression analysis. RESULTS In vitro TE was found to be dependent on the spacer length of the gemini surfactant, with the C3 spacer showing the highest activity (both 12-3-12 and 16-3-16). Both gemini cationic liposomes and gemini nanoemulsion (3x25 microg DNA/animal) produced significantly higher levels of IFNgamma in the skin (359.4 and 607.24 pg/cm2) compared to naked DNA (135.69 pg/cm2) or a liposomal Dc-chol formulation (82.15 pg/cm2). IFNgamma expression in the lymph nodes was higher in the animals treated with gemini liposomes (422.74 pg/animal) compared to the nanoemulsion formulation (131.27 pg/animal) or the Dc-chol formulation (82pg/animal). CONCLUSIONS The feasibility of topical delivery of pGTmCMV.IFN-GFP plasmid in mice using gemini cationic surfactant based delivery systems was demonstrated. IFNgamma expression after treatment with gemini-DNA formulations in the skin was 3-5-fold higher compared to the treatment with naked DNA (p<0.05), and 4-6-fold higher than the Dc-chol-DNA complex, indicating a significant advance in topical DNA delivery across intact skin in vivo.

Abstract
The skin is an attractive route for delivery of vaccines because it is accessible and contains immunocompetent cells. This opens up the possibility that, in the future, vaccines could be administered in a simple, safe and practical way without requiring the use of needles and syringes. This review focuses on the methods developed to deliver vaccines via the intact skin. Candidate vaccine antigens can be delivered topically using particulate delivery systems and patch formulations containing the antigen with an ADP-ribosylating exotoxin as an adjuvant. The duration and type of elicited immune responses depend on the antigen, the adjuvant and the method of delivery. Already, the first clinical trial of transcutaneous delivery of vaccines has demonstrated the proof of the principle. However, despite these successes, there are several challenges ahead to be addressed before vaccines administered with a patch will be available over the counter.
